Low-energy J/psi-Hadron Interactions from Quenched Lattice QCD
K. Yokokawa, S. Sasaki, A. Hayashigaki +1
The J/psi-hadron interaction is a key ingredient in analyzing the J/psi suppression in hot hadronic matter as well as the propagation of J/psi in nuclei. As a first step to clarify…
QCD Level Density from Maximum Entropy Method
Shinji Ejiri, Tetsuo Hatsuda
We propose a method to calculate the QCD level density directly from the thermodynamic quantities obtained by lattice QCD simulations with the use of the maximum entropy method (ME…
Wandering in Color-Space -- why the life of pentaquark is so long ? --
Yuu Maezawa, Toshiki Maruyama, Naoyuki Itagaki +1
The problem of the long life time of the pentaquark is investigated on the basis of the color molecular dynamics simulation. We find that it takes a long time (typically of 5…
The -meson and - Correlation in Hot/Dense Medium: soft modes for chiral transition in QCD
T. Hatsuda, T. Kunihiro
After a brief overview of the realization of chiral symmetry in hot and/or dense medium, the implications of the existence of a light scalar-isoscalar meson (which we call thro…
Low Mass Dileptons from Pb+Au Collisions at CERN SPS
Sourav Sarkar, Jan-e Alam, T. Hatsuda
We show that the dilepton spectra measured by the CERES collaboration in Pb + Au interactions for various charge multiplicities can be reproduced by a hadronic initial state with r…
Chiral Symmetry Restoration and the sigma-meson
Tetsuo Hatsuda, Teiji Kunihiro
The sigma-meson, which is at best a broad resonance in the vacuum, may suffer a substantial red-shift and appear as a soft and narrow collective mode at finite temperature and bary…
